Battery Keeper

Patented BK180

Auto Jump-Starter

No help for battery. Even jump starter works well, battery still need to be renew after the indignation. !Complicated to use. The engine hood need to be open, and battery positive and negative side need to be connected correctly every using the jump starter. It is too hard to use for ladies and elders. !Unsafe. Sparks can be triggered during storage and use. It is unsafe especially for ladies and elders. !Not reliable. Jump starter battery need to be recharged on time. What frequently happens is finding out there is low battery in the Jump starter when you need it in a hurry.

The Problems of Traditional Jump-Starter

Automatic, backstage operation at every ignition Prolong 1-5x life time of car battery, even for new battery -25 degree, Jump starter Stable, Fixed installation on the surface of Car Battery Safety, Built-in MCU control, it still safe even the positive and negative connected Easy drive, no more battery concern, especially for elders and ladies.

New Revolution Say goodbye to Traditional Jump-Starter

Battery Keeper automatic backstage operation at every ignition, user don’t need to open the engine case to jump-start the car since MCU automatically control the charging and engine start process It can much better prolong the car battery life because battery output for the engine start is much lower with the keeper’s help. Even when a dead battery with voltage lower than 10V, it could still working well with the help of battery keeper. The battery keeper can be fixed firmly on the top of car battery with cables and sticker. About the safety, the Lithium titanate is the safest battery which is used widely in electric car field, with MCU control current protection. Water proof design with compact size: 145*80*42mm

Features

BenefitEasy drive without any battery concern, especially for elders and ladies. Battery Keeper can be used widely for Taxi, Boat, JetSky, Motorcycle, Truck, and any vehicle which need battery to engine start Battery keeper can be parallel connected to generate the double or even more power for the heavy vehicle. Battery Keeper is a perfect solution for taxi, because the daily often engine start will cause original car battery die quickly. Battery Keeper have less then 2% self-discharge rate per month, and it will be a great help for long time unused car with empty car battery. Battery Keeper has almost the same performance at -25 °C as at 30°C.
